CONNECTION
WARNING:
loudspeaker connections should be only made by qualified and experienced personnel
having the technical know-how or sufficient specific instructions (to ensure that connections are
made correctly) in order to prevent any electrical danger. To prevent any risk of electric shock, do
not connect loudspeakers when the amplifier is switched on.
Before turning the system on, check all connections and make sure there are no accidental short
circuits.
The entire sound system shall be designed and installed in compliance with the current local laws
and regulations regarding electrical systems.
To ensure a correct sound reproduction, loudspeaker phase is to be respected (loudspeakers are
connected respecting the amplifier polarity).
To prevent inductive effects from causing hum, noise and a bad system working, loudspeaker lines
should not be laid together with other electric cables (mains), microphone or line level signal cables
connected to amplifier inputs.
The loudspeaker cable shall have wires (twisted, if possible, to reduce inductive effects due to
surrounding electro-magnetic fields) with a suitable section (min. 1.5 – max. 2.5 mm²) and a sufficient
electrical insulation.
